如果在 Windchill PDMLink 中发布规则配置为“default=false”，则使用 API doPublish 发布对象时不会生成 STEP 文件

<additional-files name="publish_assembly">

<file display-label="step" type="step" default="false" output-prefix="step"/>

</additional-files>

<if condition="is_assembly">

<publish additional-files="publish_assembly" on="checkin"/>
<publish additional-files="publish_assembly" on="create-representation"/>
<publish additional-files="publish_assembly" on="unknown-source"/>
<publish additional-files="publish_assembly" on="schedule"/>

</if>
